Notable Athlete Siblings That Have Been Teammates

Family and Sports go hand-in-hand. Whether it’s a whole household being passionate about one team. Or a family legacy, playing wise, being continued generation after generation (at any level). Whatever it may be, the two things go together like Butter and Toast, or Chocolate and Peanut Butter.

Currently, throughout Pro Sports, there are families that have multiple members playing. Either in the same sport, or different. Some are/have been lucky enough to be teammates at one point or another. In the MLB, San Francisco Giants relief pitchers Taylor and Tyler Rogers, are the latest siblings (and identical twins) to become teammates.

The Rogers’ brothers teaming up, got me thinking about some siblings from years past/present day, that were teammates at one point in their careers. Below, are two sets of siblings that got to enjoy that privilege at some point.

Honorable Mentions: Giannis and Thanasis Antetokounmpo (Milwaukee Bucks, 2019-present), Devin and Jason McCourty (New England Patriots, 2018-2020)

Jason and Jeremy Giambi (2000-2002, Oakland Athletics, MLB)

The Giambi brothers are, in my opinion, two of the most well known siblings in MLB History. Older Brother Jason’s 5x All-Star/1x MVP career in the outfield and first base, probably has a lot to do with that. Younger brother, the late Jeremy Giambi, wasn’t a bad player (.263 career BA, .807 career OPS). He just didn’t have the talent to keep up with the longevity in the game that Jason did. Jeremy lasted 6 seasons, while Jason played 20.

Their careers overlapped as teammates from the 2000 MLB season in Oakland. Yes, during the Moneyball years. Their time together lasted to the the middle of the 2002 season. Which is when Jeremy was traded to the Philadelphia Phillies for OF John Mabry. During their time in Oakland together, they both had very solid years throughout. In different respects though.

Jason won AL MVP in 2000, after leading the whole major leagues in Walks and OBP, along with hitting .333 with 43 HRs and 137 RBIs. The following season, 2001, when he (Jason) finished second in AL MVP voting, is when Jeremy had one of his best years. Jeremy hit .283 in 2001, only .002 points behind his career best. That same season, he had his second highest OBP, SLG, and OPS for his whole career.

Bring it back to present day and Jason is content with coaching his son’s little league team while enjoying family time in Henderson, Nevada. Unfortunately, early last year, Jeremy Giambi tragically took his own life, at the age of 47.

Markieff and Marcus Morris (2008-11, Kansas Jayhawks, NCAAB. 2012-15, Phoenix Suns, NBA)

Like the aforementioned Rogers brothers, the Morris brothers are also identical twins. Markieff is older than Marcus by a whole seven minutes. Being twins, they got lucky enough to play together at the University of Kansas, for all three years they were there. I think it’s safe to say that the Morris’ are two of the best players Kansas has seen in the past 25 years, at least.

Markieff is 18th on KU’s all-time rebounding list, and 17th on their all-time blocks list. In his junior season, the elder brother averaged 13.6 Pts, 1.1 Blks, and 8.3 Rebs. Garnering a Big 12 All-Second Team selection. Marcus was the better player overall as a Jayhawk. He averaged 17.2 points, 0.8 Blks, and 7.6 Rebs in his junior season. Leading to him being named Consensus All-America Second Team, a Wooden Award All-American, and Big 12 Player of The Year.

In the 2011 Draft, the brothers were coincidentally enough chosen one after the other. Markieff, was chosen 13th overall by the Phoenix Suns. Marcus, was chosen 14th overall by the Houston Rockets. They joined forces once again, part-way through the 2012-13 season when Marcus was traded to Phoenix for a 2nd-round pick.

Both player’s production started to ramp up around the same time. In 2014-15, their last season together they had solid stat-lines.

Markieff’s 2014-15 stat-line: Played all 82 games. Averaged 15.3 Pts, 2.3 Ast, and 6.2 Reb.

Marcus’s 2014-15 stat-line: Played 81 out of 82 games. Averaged 10.4 Pts, 1.6 Ast, and 4.8 Reb.

Before the start of the 2015-16 season, Marcus was traded to the Detroit Pistons along with Danny Granger, and Reggie Bullock for a 2nd round pick in 2020. Thus ending the brothers time as teammates. Today, Markieff is a role player for the Brooklyn Nets, and Marcus is the starting PF for the Los Angeles Clippers.

Those are just a couple of sibling teammates from the long list throughout sports history.
